Live Conference Call to be Held at 8:00 PM U.S. Eastern Time, May 22, 2014

BEIJING, May 22, 2014 (GLOBE NEWSWIRE) -- 21Vianet Group, Inc. (Nasdaq:VNET) ("21Vianet" or the "Company"), the largest carrier-neutral internet data center services provider in China, today announced its unaudited financial results for the first quarter of 2014. The Company will hold a conference call at 8:00 p.m. Eastern Time on May 22, 2014. Dial-in details are provided at the end of the release.

First quarter 2014 Financial Highlights

Net revenues increased by 34.5% to RMB586.0 million (US$94.3 million) from RMB435.7 million in the comparative period in 2013.

Adjusted EBITDA1 increased by 40.9% to RMB112.9 million (US$18.2 million) from RMB80.1 million in the comparative period in 2013.

Adjusted EBITDA margin2 increased to 19.3% compared to 18.4% in the
comparative period in 2013.

Mr. Josh Chen, Founder, Chairman and Chief Executive Officer of the Company, stated, "We are off to a solid start in 2014, thanks to the groundwork we completed in 2013 for both our IDC and cloud businesses. With the addition of 1,033 cabinets to our self-built data centers in the first quarter, we're pleased to continue our structural shift to more self-built data centers. Following the public previews last year, we commercially launched Microsoft Azure in March 2014 followed by Office 365 in April 2014, delivering for the first time a comprehensive commercial suite of enterprise-grade public cloud services in China. During the quarter, we were able to secure thousands of clients for both services, while also migrating numerous large enterprises to long-term contracts, which will help us accelerate the growth of our cloud business revenues. As we remain on track to deploy a total of
10,000 cabinets by the end of 2014, bringing us to approximately 25,000 total cabinets, we believe that our partnership with Foxconn Technology Group will help us further hasten our efforts in IDC construction as well as developing innovative cloud services that target the Chinese market. We will continue to build upon the strong foundation we have established and are confident in our position as an integrated internet infrastructure services provider offering innovative products and solutions for our customers."

Mr. Shang-Wen Hsiao, Chief Financial Officer of the Company, commented, "We are very pleased to further improve our utilization rate, revenue growth rate and adjusted EBITDA margin to 73.8%, 34.5% and 19.3%, respectively, in the first quarter. These improvements were supported by our increasing mix of higher margin self-built facilities, enhanced data transmission following our network upgrades and incremental contributions from cloud services. This performance was fueled by the ongoing strong customer demand for our IDC services and improved sales throughout China. As we continue to ramp up our capacity, deepen our market footprint in 2014 and complete our scheduled commercial launch of IBM's private cloud services around mid-year 2014, we believe that we are well-positioned to capitalize on favorable secular trends associated with China's dynamic and evolving data center and cloud
services market."

First quarter 2014 Financial Results

REVENUES: Net revenues for the first quarter of 2014 increased by 34.5% to RMB586.0 million (US$94.3 million) from RMB435.7 million in the comparative period in 2013.

Net revenues from hosting and related services increased by 52.8% to RMB404.4 million (US$65.1 million) in the first quarter of 2014 from RMB264.7 million in the comparative period in 2013, primarily due to an increase in the total number of cabinets under management, an increase in demand for the Company's CDN services as well as the incremental contributions from cloud services. Net revenues from managed network services increased by 6.2% to RMB181.6 million (US$29.2 million) in the first quarter of 2014 from RMB171.0 million in the comparative period in 2013 driven by an increase in network capacity demand for data transmission services.

GROSS PROFIT: Gross profit for the first quarter of 2014 increased by 38.4% to RMB160.6 million (US$25.8 million) from RMB116.1 million in the comparative period in 2013. Gross margin for the first quarter of 2014 was
27.4%, compared with 26.6% in the comparative period in 2013 and 26.4% in the fourth quarter of 2013. The increase in gross margin was primarily due to an increase in utilization rates and incremental revenue contributions from cloud services.

Adjusted gross profit, which excludes share-based compensation expenses and amortization of intangible assets derived from acquisitions, increased by 36.2% to RMB171.1 million (US$27.5 million) from RMB125.6 million in the comparative period in 2013. Adjusted gross margin increased to 29.2% in the first quarter of 2014 from 28.8% in the comparative period in 2013 and 29.0% in the fourth quarter of 2013.

OPERATING EXPENSES: Total operating expenses were RMB280.9 million (US$45.2 million), compared with RMB89.2 million in the comparative period in 2013.

Sales and marketing expenses increased by 39.5% to RMB42.4 million (US$6.8 million) from RMB30.4 million in the comparative period in 2013, primarily due to the expansion of the Company's sales and service support team and the Company's marketing efforts associated with the launch of Microsoft's premier cloud services.

General and administrative expenses increased to RMB179.4 million (US$28.9 million) from RMB45.3 million in the comparative period in 2013, primarily due to one-time share-based compensation expenses in connection with shares granted to certain management employees of the Managed Network Entities.

Research and development expenses increased by 58.5% to RMB25.2 million (US$4.1 million) from RMB15.9 million in the comparative period in 2013, which reflected the Company's efforts to further strengthen its research and development capabilities and expand its cloud computing service offerings.

Change in the fair value of contingent purchase consideration payable was a loss of RMB33.9 million (US$5.5 million) in the first quarter of 2014, compared with a gain of RMB2.3 million in the comparative period in 2013. This non-cash loss was primarily due to an increase in the market value of the Company's shares, which resulted in an increase in the fair value of share-based contingent purchase considerations payable as of March 31, 2014 associated with the Company's past acquisitions.

Adjusted operating expenses, which exclude share-based compensation expenses and the changes in the fair value of contingent purchase consideration payable, increased to RMB109.9 million (US$17.7 million) from RMB80.0 million in the comparative period in 2013. As a percentage of net revenue, adjusted operating expenses were 18.8%, compared with 18.4% in the comparative period in 2013 and 18.7% in the fourth quarter of 2013.

ADJUSTED EBITDA: Adjusted EBITDA for the first quarter of 2014 increased by 40.9% to RMB112.9 million (US$18.2 million) from RMB80.1 million in the comparative period in 2013. Adjusted EBITDA margin for the quarter increased to 19.3% from 18.4% in the comparative period in 2013 and 18.8% in the fourth quarter of 2013. Adjusted EBITDA in the first quarter of 2014 excludes share-based compensation expenses of RMB138.7 million (US$22.3
million) and changes in the fair value of contingent purchase consideration payable of RMB33.9 million (US$5.5 million).

NET PROFIT/LOSS: Net loss for the first quarter of 2014 was RMB151.4 million (US$24.4 million), compared to a net profit of RMB12.0 million in the comparative period in 2013. The decrease in net profit was mainly due to an increase in the aforementioned one time share-based compensation expenses, non-cash loss in the fair value of contingent purchase consideration payable versus a non-cash gain in the comparative period in 2013 and an increase in interest expense.

Adjusted net profit for the first quarter of 2014 increased by 6.1% to RMB33.0 million (US$5.3 million) from RMB31.1 million in the comparative period in 2013. Adjusted net profit in the first quarter of 2014 excludes share-based compensation expenses of RMB138.7 million (US$22.3 million), amortization of intangible assets derived from acquisitions of RMB8.8 million (US$1.4 million), and changes in the fair value of contingent purchase consideration payable and related deferred tax impact of RMB36.9 million (US$5.9 million) in the aggregate. Adjusted net margin was 5.6%, compared to 7.1% in the comparative period in 2013 and 7.5% in the fourth quarter of 2013.

EARNING/LOSS PER SHARE: Diluted loss per ordinary share for the first quarter of 2014 was RMB0.38, which represents the equivalent of RMB2.28 (US$0.37) per American Depositary Share ("ADS"). Each ADS
represents six ordinary shares. Adjusted diluted earnings per share for the first quarter of 2014 was RMB0.08, which represents the equivalent of RMB0.48 (US$0.08) per ADS. Adjusted earnings per share is calculated using adjusted net profit as discussed above to divide the weighted average shares number.

As of March 31, 2014, the Company had a total of 398.7 million ordinary shares outstanding, or the equivalent of 66.4 million ADSs.

BALANCE SHEET: As of March 31, 2014, the Company's cash and cash equivalents and short-term investment were RMB2.3 billion (US$370.7 million).

First quarter 2014 Operational Highlights

Monthly Recurring Revenues ("MRR") per cabinet was RMB10,753 in the first quarter of 2014, compared to RMB10,694 in the fourth quarter of 2013.

Total cabinets under management increased to 15,074 as of March 31, 2014, from 14,041 as of December 31, 2013, with 9,792 cabinets in the Company's self-built data centers and 5,282 cabinets in its partnered data centers.

Utilization rate was 73.8% in the first quarter of 2014, compared to 71.2% in the fourth quarter of 2013.

Recent Developments

In April 2014, the Company entered into a strategic partnership agreement with the leading global electronics manufacturer, Foxconn Technology Group ("Foxconn").

In addition, the companies will jointly cooperate to develop innovative cloud services targeting the Chinese market. The companies will also be jointly responsible for the supply chain management of the Company's IDC projects, including design, development, manufacturing, and construction of Internet data centers.

Also in April 2014, the Company appointed Mr. Eric Chu, a telecommunications and internet infrastructure analyst, as Vice President of Capital Markets and Business Development. Mr. Chu will lead the Company's investor relations team in communicating the Company's operating strategy, business initiatives and growth opportunities to the investment community, while also exploring strategic partnerships with industry participants.

The Company has commercially launched Microsoft Corporation's premier cloud services in China, with Azure services being made generally available to all paying customers in China in late March 2014. Operated by 21Vianet, Microsoft's cloud represented the first global public cloud service available for massive commercial adoption in China.

In addition, also in April 2014, the Company announced that Microsoft Corporation's Office 365 services are made generally available to all paying customers in China, delivering for the first time the familiar Office productivity suite, now equipped with more advanced communication and collaboration tools, as a local cloud service to business and government customers throughout China.
